Step 2. Create association of Altium Designer with DBLINK files

If, despite the installed application, the DBLINK file does not start in the Altium Designer application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Altium Designer application as the default for handling the DBLINK file.

Step 3. Update Altium Designer to the latest version

If, however, after binding Altium Designer with Altium Designer Database Link there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Altium Limited. website and install the latest version.

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The DBLINK file may be unusually small compared to the original file. Usually this applies to DBLINK files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the DBLINK file that we want to open. Sometimes virus-infected DBLINK files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the DBLINK file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair DBLINK file corruption. The easiest way to restore the file is from a backup or by contacting Altium Limited., but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted file DBLINK except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move DBLINK to a different directory.
This problem usually affects more complex files. In this case, the DBLINK file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the DBLINK file again. However, some background programs may block the DBLINK file while scanning. If nothing helps, please reset the device.
